Abstract

The invention discloses a composite protection sleeve material with added carbon fibers for a high-shielding data line. The composite protection sleeve material is composed of, by weight, 100-104 parts of SEBS, 65-68 parts of paraffin oil, 29-31 parts of polypropylene, 21-23 parts of maleic anhydride grafted polypropylene, 3-4 parts of antioxidant B215, 81-83 parts of magnesium hydrate, 4.3-5 parts of expanded graphite, 1.6-1.7 parts of silane coupling agent A-171, 8-9 parts of absolute ethyl alcohol, 2-3 parts of zinc borate, 8-9.5 parts of natural rubber, 13-15 parts of carbon fiber, 4-6 parts of superfine carbon black, 2-2.5 parts of sodium dodecyl benzene sulfonate and a proper amount of distilled water. According to the composite protection sleeve material with the added carbon fibers for the high-shielding data line, the blend of the paroline, the modified SEBS and the polypropylene serves as the base, in the process of processing the surfaces of the carbon fibers and the superfine carbon black and adding the carbon fibers and the superfine carbon black to a product, the dispersibility of powder can be improved, meanwhile, a very good shielding effect is achieved, the bending resisting performance of the product can be improved, and the composite protection sleeve material can be used for manufacturing flexible lines such as data lines.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a composite sheath material for high-shielding data lines with added carbon fibers and a preparation method thereof. Background technique [0002] At present, more than 90% of the electronic wire sheath materials, insulating materials and electronic plug materials widely used in the domestic electronic and electrical industry are made of PVC. However, since July 1, 2006, the European Union has issued a decree to prohibit the entry of electronic and electrical products containing certain harmful substances such as halogen flame retardants and heavy metals into the European market. This has had a serious impact on the export of electronic and electrical products in my country. While the European Union issued its ban, some foreign companies have begun to vigorously promote their products to my country's electrical industry, trying to seize the Chinese market. Under this fo...
